This would be useful for opensource hardware projects (aimed at beginners) to literally see how things are wired together. I'm still not at the schematic phase myself. But I use MS Paint wiring diagrams.
OMG the wires flex, damn
Less for theory more visually "this wire goes here"
There’s also the other thing of being able to read documentation. If one wants to use some module in one’s project, the datasheet and application notes aren’t going to have breadboard-centric illustrations, they’re going to have schematics (or at least abstracted ones). I presume you come from a programming background, and so would know the importance of being able to read documentation, and knowing that if you can’t do that you’re pretty much dead in the water.
The hard part of learning about electronics is not identifying the components but getting a good understanding of what is happening in the circuit. For that, it’s better to have a learning tool which displays voltage and current at every part of the circuit all the time. Rather than something which prioritises looking like what you’d have on your desk as a constraint for its method of visual representation.
